EL3681 and KL3681 I/O terminals

The new EL3681 and KL3681 terminals: By integrating digital multimeters directly into I/O nodes, users can expect a streamlined and low cost alternative to stand-alone digital multimeters. The modules provide high precision and simple, high-resistance measurement from 300 mV to 300 V and cost just $305. Using the digital multimeter terminals with fieldbus interface for measuring current and voltage, measured values can be processed directly in the I/O system or by the master controller. These dynamic measuring terminals are available for the Beckhoff Bus Terminal system, which offers support for most major fieldbuses, as well as for the high performance EtherCAT Terminal system. Equipping industrial systems with the Beckhoff KL3681 (Bus Terminal) and EL3681 (EtherCAT Terminal) significantly increases flexibility with the wide input range and automated measuring range selection. The digital multimeter terminals measure DC and AC voltages; in the case of AC voltage, the effective (RMS) value is determined.
